Just so we are singing from the same song sheet
You are saying that the drive belt, the top one that connects to the hydros jumps off when you turn the belts on ?

All the belts engage fine but the hydro belt comes off while I'm mowing.

Okay this particular Hustler setup can be cause by several problems. Loose transaxle mounting bolts (screws), Hydro fan blades that have drooped,hitting the drive belt. And single most troublesome part is the little 2 inch idler pulley bearings failing. Being only 2 inches it is operated at overspeed of the bearing rating. Also check the drive belt idler arm for wear.

Referencing Model 938381.

Had one doing the same thing , the tension spring was stretched and no longer keeping the belt tension up, Still throwing the belt , found a missing mounting bolt on one of the hydro motors , replaced the bolt and problem went away
